JOSEPH F. DONKIN, OF GRAYSON, CALIFORNIA.

IMPROVEMENT IN MlLK-STRAINERS.

Specification formingpart of Letters Patent No. 152,981, dated July14,1874; application filed 'February 16, 187 4.

To all whom it may concern:

Be it known that I, JOSEPH F. DoNKIN, of Grayson, Stanislaus county,State of Galifornia, have invented a Strainer for Milk- Fails, &c.; andI do hereby declare the following description and accompanying drawingsare sufficient to enable any person skilled in the art or science towhich it most nearly appertains to make and use my said inventionwithout further invention or experiment.

My invention rela-tes to an improvement in strainers, such as may beused for milk-pails and in other places 5 and it consist-s in the useot' an elastic wire or other spring, around which gauze of the strainerisiitted, and the whole is then inserted into a sort ot' hoop or recesswhich is formed in the bottom, or the spout where the strainer is to beused, so that the latter is at all times easily removable when worn out,or for the purpose of cleanin 0.

Referring to the accompanying' drawings for a more complete explanationof my invention, Figure l is a perspective view, showing my strainerattached to a pail. Fig. 2 is a seetion. Fig. 3 is a plan view. Figs. 4and 5 show its application to other vessels.

A is a pail to which my strainer is to be attached. B is thedischarge-spout, which is secured to the top of the pail, as shown. Thisspout may be struck up by a die, and will then have a recess formed, asat C. I then make an elastic ring, D, of metallic wire or other suitablesubstance which can be compressed, so as to be placed in the recess orhoop C, where its elasticity will retain it firmly. To this ring Isecure the gauze or wire cloth E of the strainer, generally by ioldingor winding it about the spring-wire, and the whole can then be placed inthe recess, where it will remain firmly seated.

By this construction I ain enabled to con struct a strainer which can beeasily removed at any time for the purpose of cleaning, and when thegauze is worn out it can be easily replaced without having recourse to atinshop. g

lt will be manifest that my strainer is easily applied to the side of apail, or to the bottom of any vessel which may be used as a strainer,with but slight modication.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

-A strainer consisting of the wire cloth or gauze E, secured to anelastic expanding hoop, D, and placed in the recess or hoop C,substantially as and for the purpose herein described.

In witness whereot'I hereunto set my hand and seal.

JOSEPH FOSTER DONKIN.
